Wl NDOW-VENTI LATOR FO R RAl LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 275,271, dated April 3,1883.

Application filed May 9, 1882. (No model.)

. To all whom it may concern:

Be it known that I, HUMPHREY H. REY- NoLDs,acitizen oftheUnited Statesof America, residing at Minneapolis,in the county of Hennepin and Stateof Minnesota, have invented certain new and useful Improvements inWindow-Ventilators for Railway-Oars, of which the following is aspecification.

My invention relates to imprevements in window ventilators, particularlyadapted for railway-cars.

The object of my invention is to provide a simple and inexpensive deviceto be placed under the sash of a window for the purpose of thoroughlyventilating the car without causing a draft and without the admission ofcinders, gnats, 850.

To this end my invention consists in a novel construction andarrangement of parts, as hereinafter fully set forth.

In the accompanying drawings, Figure l is an elevation of my improvedventilator in place. Fig. 2 is a plan view ofthe same, showing themanner of putting itin position. Fig. 3 is a longitudinal sectionalelevation, Fig. 4 a cross-sectional elevation, and Fig. 5 a horizontalsectional View, of the device removed.

Similar letters of reference refer to similar parts throughout theseveral views.

In the drawings, A and A are frames, of wood or other suitable material,hinged together by hinges h h, and are of such a length that when openedout, as shown in Fig. 5, the combined length is just equal to the widthof the sash under which it is to be placed. These frames A and A arecovered outside and inside with wire-cloth \V and W, leaving a space, 8,between. {See Fig. 5.) The wirecloth on the outsideiscomparativelycoarse, while that W on the inner surface is very fine.Through the bottom of the frames Aand A, and opening into the space 8,between the wire-cloths \V and W, are a series of small openings, 0 0,around which are placed semicylindrical deflectors a, of progressiveheights, as shown in Fig.3. On the bottom of the frames are small piecesI) b, of rubber or other suitable material, to prevent the frame fromcoming down on the window-sill when in position and closing the openings0, 8:0. The thickness of the frames at the ends 0 e and at the bottom 1)corresponds to the thickness of the sash in the window in which it is tobe used.

The device is placed in position and operates in the manner described asfollows: The sash is first raised and the ends 6 c inserted between thewindow-strips f f by turning the frames A and A on the hinges h h in theposition shown in Fig. 2. The frames are then turned straight andpressed down between the window-strips until the pieces I) I) rest onthe window-sill, the lower edge of the frames coming below the strip orledge thereon. The sash is then lowered until it rests on the upper edgeof the frame, holding it firmly in position.'

If desired, a strip of rubber or other suitable material may be placedon the top edge of the frame or on the bottom of the sash to insure atightjoint.

The device is to he placed in the window with semi-cylindricaldeflectors a, over openings o, facing in the direction in which thetrain is going. The coarser or outside screen, W, arrests all cinders,&c., and partially stops the draft which enters into the space s, and byreason of the forward movement of the train strikes the deflectors a andcreates a current through the openings 0 and space left below the bottomof the frames by reason of the pieces I) b, while the cool, refreshingair there from is diffused through the fine screen W into the car freefrom cinders, dust, and such impurities.

The device,it will be observed, is very simple and may be readilyapplied or removed, and adds greatly to the comforts of travelers. isadapted for use on all classes of railwaycoaches including parlor,dining-room, and sleepers, and when not in use may be folded togetherand occupies but little space.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a window-ventilator, the combination, with the hinged frames, ofthe wire screens of different degrees of fineness, substantially as setforth.

2. In a window-ventilator, the combination, with theframe A, of thescreens W W, with meshes of difierent sizes, and the space 8, inclosedbetween said screens, substantially as shown and described.

3. In a window-ventilator, the combination,
